Remote System Upgrades with Stratix II and Stratix II GX Devices
■ The enhanced configuration device features an error checking
mechanism to detect instances when the FPGA fails to detect the
configuration preamble. In these instances, the enhanced
configuration device pulses the nSTATUS signal low, and the remote
system upgrade circuitry attempts to load the factory configuration.
Figure 8–10 shows a system block diagram for remote system
upgrade with enhanced configuration devices.

Notes to Figure 8–10:
(1) Connect the pull-up resistor to a supply that provides an acceptable input signal
for the device.
(2) Connect RUnLU to GND or V_CC to select between remote and local update modes.
(3) Connect MSEL[3..0] to 0100 to enable remote update remote system upgrade
mode.
Stratix II and Stratix II GX devices offer remote system upgrade
capability, where you can upgrade a system in real-time through any
network. Remote system upgrade helps to deliver feature enhancements
and bug fixes without costly recalls, reduces time to market, and extends
product life cycles. The dedicated remote system upgrade circuitry in
Stratix II and Stratix II GX devices provides error detection, recovery, and
status information to ensure reliable reconfiguration.
